6813.20.00.15 - Other

This HTS category, 6813.20.00.15, specifically covers "other" friction materials and articles thereof, not mounted, used for brakes, clutches, or similar applications. These items are characterized by having a basis of asbestos, other mineral substances, or cellulose, and may incorporate textile or other materials. The "other" designation signifies that these friction articles do not fall under more specific subheadings at this level, and are not intended for specialized applications like those for civil aircraft.

The key differentiator for this category lies in its broad applicability to general-purpose friction components. While sibling categories might exist for highly specialized uses (such as components for civil aircraft under 6813.20.00.10), this classification encompasses the vast majority of unmounted brake linings, pads, segments, discs, washers, and similar items where the friction material is not asbestos-based but derived from other mineral substances or cellulose. The presence of asbestos in the material composition is a primary criterion for inclusion within the broader heading 6813.20.

As a leaf node, 6813.20.00.15 does not have further subdivisions. Therefore, classification into this code relies on a thorough assessment of the material composition (non-asbestos mineral or cellulose-based), the form of the article (sheet, roll, strip, segment, disc, washer, pad, etc.), and its intended application as a friction component for braking or clutching mechanisms, excluding specialized uses covered elsewhere. The "other" designation within the description confirms its role as a residual category for such articles not explicitly enumerated in other subheadings.
